That the tub may be adjusted between its described positions, a segmental gear I is secured thereon as at one end, and amotor ll arranged to drive the gear it through any suitable gearing such as that illustrated. That washing liquid may be supplied to the tub, and quickly, piping I8 is arranged to deliver through openings I! in the base 6 at both ends of the tub; and. that the entering liquid be kept clear so faras possible from the cylinder and tub bearings, pipes 24 are arranged to lead fromrthe passages is downwardly as shown Fig. 8. Both cylinder and tub are operated by power, each by its own driving motor, control of both motors being semi-automatic, subject to the will of the operator, and also for safety subject to certain interlocking arrangements to be described.

1 The cylinder-driving motor 2 ha an associated casing 2| within which are located some of its control switches including an automatic reversing drum contact mechanism 2| timed with the motor as by any suitable connecflon including the chain drive indicated at 22'. The cylinderreversing mechanism is indicated Fig. 9, and the arrangement as later described in greater detail will be recognized by one familiar with the art, as adapted to effect periodic reversal of the cylinder during the washing operation. A motor brake indicated at 22 may be included inthe control means for maintaining the cylinder pod tion when its motor is oil.

A switch 24 is provided, and arranged to be automatically closed when the tub doors are fully closed, and to be otherwise open. vThis switch 24 is in circuit with a two-button stopand start switch 25, which-is a control circuit for placing the cylinder in automatic reversing operation. The arrangement is such that both switches 24 and 25 must be closed. before the cylinder may have. operation. 25 is thus a hand-operated switch by which the operator may initiate automatic cylinder-reversing operation by placing the switch in the full-line position of Fig. 9, but only if the tub doors be fully closed.

26 is an automatic self-closing switch arranged to be held open only when the tub'doors are fully closed as shown in Fig. 1. It is in series circuit with the start-stop switch 25 so that its circuit may be closed only when the switch 25 is in stop position (broken lines, Fig. 9) and thus the cylinder stationary. When the switch 28 is closed it. places the push button switches 21, 28 and 20 incircuit for hand control of the cylinder drive motor 5 for operation of the latter to move the cylinder subject to hand operation and manipulation of the switchs 21, 2. and 2!.

' Switches 21 and 21 are placed in circuit through drum contacts ll and II. These hand-operated switches are located in a control board convenient to the operator at the front of the machine as shown Figs. 1 and 2.

The switches 21 and a, when either is demotor the arrangement being (me whereby, by

alternate operation of switch. 2l'and 24,

Switch 29 is an emergency switch whereby the cylinder may be operated in reverse direction in case of accident, though the tub doors be open.

Adjustment of the tub through the operation of its motor I1 is controlled as follows: A cam 33' is secured upon the tub for actuating engagement, as the tub moves, with the operating levers of a number of automatic switches I4, 35, II and 42, mounted on the baseframe and shown Figs. 2 and 9. A push button switch 32 provided on the control board of'the machine is arranged to efiect closing of the circuit of the tub drive motor H to move the tub forwardly, clockwise, from the washing position of Hg. 4 to the drain position Fig. 6f As the tub attains the drain position its cam 33 engages the actuating lever of the switch 34 to open this normally closed switch. Switch 35 is biased toward closed position but is held open when the tub is in normal washing position as shown in Fig. 2. Switch 35 closes as soon as the tub leaves this position to set up'a circuit (later described) by which the motor -i|' automatically reverses and returns the tub counterclockwisefrom draining position. As the tub resumes its washing position the cam 33 engages the switch 35 to open its circuit and stop the tub.

A push button switch 4i is also provided onthe control panel, in the circuit of the tub-actuating motor ll. This switch effects adjustment the.

tub from loading position. that of. Fig. 5, to dumping position, that of Fig. 'I. As the tub attains dumping position, following operation of thepush button 4|, its cam 33 engages the actuating lever of' the switch 42, opening the motor circuit andthus automatically stoppingthe tub in dumping position.

A push button switch 43 is provided in the tub motor circuit for returning the tub from dumping position to loading position. Closing of the switch 43 by depressing its button causes reverse.

As will beappreciated by one familiar with the I art. and as is indicated Fig. 9, the described operator-operated push button switches arein control circuits and not in .the main motor cirq cults. The usual line cut-out switches. 53 are provided and a safety switch 52 is preferably located on the control board for convenient reach by the operator to stop all motor operation in emergency.

Operation will be as follows, commencing with the cylinder empty, its compartment doors and the tub. doors open and the parts otherwise positioned as in Fig. 5.

The near compartment is loaded with work and its door 5 closed. Push button switches 21:

and 28 are next successively closed to rotate the cylinder forwardly in two steps of each,

bringing the next compartment'into registry with the tub opening. This second comment is loaded, its door closed, and the same procedure followed in loading the third compartmen The cylinder is then completely loaded.

Detergent liquid having been introduced into the tub to the proper level, by way of the pipe I8, the tub doors II are closed. This closes the switch 24 in the cylinder motor circuit, opens the switch 26, and the cylinder is started in its automatic reversing operation in the washing cycle by throwing the switch to the full line position of Fig. 9. v

The work in the several compartments is tumbled about, successively submerged and raised from the liquid as in the usual manner of operation of washing apparatus having this type of cylinder. During the washing operation changes of liquid as from detergent to rinsing liquid, are made by the operators depressing the drain button 32. When the tub is in washing position splash caused .by cylinder operation does not result in loss of liquid because the drain opening I2 is closed by the cover I3. Depression of the drain button causes rotation of the tub from the position of Fig. 4 to that of Fig. 6, with automatic return to that of Fig. 4, the cylinder continuing in its automatic operation during this tub adjustment. Each such tub adjustment effects drainage of the tub liquid, which is replaced by new liquid through the pipe I8.

After the washing operation, the cylinder is stopped by throwing the switch 25 tothe broken line position of Fig. 9. The tub doors I I are next fully opened to the position of Fig. 5, which automatically opens the switch 24 so that the cylinder cannot be restarted into automatic operation, and closes switch 26 in the forward operating circuit of the cylinder motor subject to the push button switches 21, 28 and 29. Depression of the switch 21 adjusts the cylinder forwardly or counterclockwise, Figs. 4 to '7, until its nearest compartment registers with the tub opening, and consequently until the door 5 of such compartment, which is then closed, registers with the lower or forward half of the tub opening as in Fig. 5. This compartment door is then opened by the operator.

The tub is next adjusted to theposition of Fig. 7 by depression of the push button switch 4I. Depression of the switch button 21 or 28 now causes 60 advance of the cylinder from the position of Fig. 5 to that of Fig. 7 which permits the work in the near compartment to slide outwardly through the door opening of the compartment into suitable means provided for transporting the work away from the machine. The other push button 21 or 28 is next depressed causing 60 advance of the cylinder 'to bring its next compartment to the position of Fig. 5. After opening of the door of this second compartment the cylinder is again advanced, as in the case of the first compartment and its load permitted. to be discharged by gravity. The. third compartment is emptied in the same manner, leaving the parts as in Fig. 7 and the machine ready to be reloaded for the next washing operation. This completes the cycle of the machine.

The control circuits through which themachine is operated in the normal operating cycle are as follows:

Assume the machine loaded, the doors closed and therefore the interlocking switches completing the circuits for which they are intended and the line switches 53 both closed thus establishing an electric service to the machine. Closure of a safety switch 52 starts the machine by establishing the starting circuit.

Starting circuit.From source LI through line IOI, pilot fuse, line I02. safety switch 52, line I 03, transfer switch 25 (in run position, full lines, Fig. 9), line I04, tub door interlock switch 24, line I05, line I06 line I01, coil of-transfer relay, line I08, line I09, line IIO, line III, through safety switch 52, line II 2, overload relay contact H2, line II3, pilot fuse, line II4 to source L3.

This circuit energizes the coil of the transfer relay effecting opening of the two normally closed contacts and closure of the three normally open contacts which are incorporated in this relay.

The closure of the relay contacts establishes additional circuits as follows:

Brake release from source LI through line I0 I, pilot fuse, line I02, safety switch 52, line I03,

' transfer switch 25, line I04, door switch '24, line I05, line I06, transfer relay contacts, line I2I, line I22, brake coil 23, line I23, line .I09, line H0, line III, safety switch 52,'line II2, over- 7 load relay contact II2, line II3, pilot fuse, line II4 to source L3.

The energizing of the brake coil which is electro-magnetic type releases the brake shoes and maintains the shoes released as long as the circuit through the coil maintains.

. Cylinder motor (9) reversing circuit (forwardrotation) .--From source LI, line "I, pilot fuse,

line I02, safety switch 52, line I03, transfer switch 25, line I04, door switch 24, line I05, line I06, contacts of transfer relay, line I3I, through contacts B of motor driven reverse drum, line I32, line I33, coil F of contactor, line I34, line I35, line I I I, safety switch 52, line I I2, overload relay contacts II2', line II3, pilot fuse, line II4 to source L3.

The effect of these motor reversing circuits is to alternately and at predetermined times cause closure of the forward and reverse contacts which are part of the controller and in this way accomplish reversing of the machine through the reversing of the cylinder drive motor 9).

Cylinder motor (9) accelerating circuit.--From source LI through line IOI, pilot fuse, line I 02, safety switch 52, line I03, transfer switch 25, line I04, door switch 24, line I05, line I06, through contacts of transfer relay, line I39 to contacts C of motor driven reverse drum, line I40, contactor coil G, line I35, line I I I, safety switch 52, line II2,

remove. from-the circuit at predetermined times the reactance in series with the motor windings.

'This reactance reduces the voltage and consequently the torque of the motor at the moment of reverse and lessens the shock .to the machine.

The reversing controller disclosed and the transfer relay which is part of this control are old and well known in the art.

opening of tub door switch 24 etc. and the circults outlined represent the normal circuits required by the machine. during the normal wash- Assuming that the washing operations have been completed and the machine is to be unloaded, the first step required is to dump the washing liquids from the tub and this is accomplished by moving the tub through circuits established as follows:

' Tubmotor dump clrcuit.From source LI line ment over and toward the operator of the tub,

"I, pilot fuse, line I52, safety switch 52, line I55, transfer-switch 25, line I55, door switch 25, line I5I, push button 52, depressed by the operator, line I52, line I52, tub movement limit switch 55, line I55, normally closed push button ll, line I55, line I55, coil D of contactor, line I5'I, line I55, line III, line III, safety switch 52, line II2, overload relay contacts, line III, pilot fuse, line H5; to source L5.

The energizing of the contactor coil D closes the contacts which energize the motor II for moving the tub and causes the tub to move through a predetermined arc. As the tub is moved the drain opening moves from the normal position, above the center line of the machine, to an approximate low vertical position and the liquids flow through this opening into the drain underneath the machine.

As soon as the tub starts itsdumping movement switch closes so as-to establish a circuit for energizing contactor coil D as soon as switch I closes.

When the tub reaches the predetermined point of maximum movement switch 35 is mechanically opened which deenergizes coil D and permits switch I55 to close.

The closure of switch I59' initiates the following circuit, the purpose of which will be given after the circuit is outlined.

Tub motor reverse circuit-From source LI- establishing circuit to the tub moving motor (I1) causing reversal of the direction of rotation of such motor and the return of the tub to its original position with the dump opening again above the center line of the machine.

When the tub reaches this normal position the described circuit is interrupted by the mechanical opening of switch 55.

It will be noted that there is a possibility of the contactor: opening due to a momentary opening of a switch in the energizing circuits therefon. To

insure continuity of feed to the contactor coils in,

such a contingency, an auxiliary feed is provided from source Ll through line 2| I, such feed being established and maintained only as long as either of the contactors are closed.

The machine is now ready for the withdrawal of the work which has been processed and the next I step toward this is the opening of the tub doors manually to provide access to the cylinder within which the clothes were processed. With the tub doors fully opened the tub is rotated to a prede-' termined dumping position. The circuit through which this is accomplished being:

Tab motor unloading circuit-From source LI,

line III, pilotjfuse, line I52, safety switch 52, line I55, transfer switch 25, manually moved to inching position (broken lines, Fig. 9) line "5, switch 25, closed by opening of tub doors, line I'II, line 25!, contacts of pushsbutton II, depressed by opwater, line 255, switch 52, line 255, line I55, coil Dof contactor,line I5'I,line I55, line 5, line III, safety switch 52, line I I2, overload relay contacts, line 5, pilot fuse, line IlltosourceLl.

The establishment of this circuit causes movesuch movement continuing as long as the opera-' tor maintains push button 5| depressed or until the maximum predetermined movement has occurred when switch 52 is mechanically opened, interrupting the circuit and stopping movementof the tub. s To obtain opposite movement of the tub if needed a second circuit is provided, being:

Tub motor reversing circuit-From source LI, line I5I, pilot fuse, line I52, safety switch 52, line I55, transfer switch 25, line "5, door switch 25, line I'll, line 25l, line 252, contacts of push button 52, depressed by operator, line 255,- switch 55', line 255, line I55, coil D of contactor, line I55, line I55, line IIII, line III, safety switch 52, line II2, overload relay contacts, line II5, pilot fuse, line Ill to source L5.

, This circuit closes the contactor which gives reverse movement of -tub drive motor", such movement continuing as long as the push button is maintaineddepressed or until the limit of allow- I able movement is reached at which time switch 35' is opened and stops further movement of the tub.

Having, as indicated in the foregoing, brought the tub to the required position for the unloading of the machine, the next requirement is to move the cylinder and the various pockets thereof to registry with the tub opening and in proper positions for the dumping of the load from the cylinder and the introduction of new work into the cylinder for process-n8 As the cylinder disclosed is multi-pocket type this requires the registry of the cylinder through a number of positions and the circuits required are as outlined below.

y The opening of the tubdoors have mechanically caused the opening of switch 25 and the closure of switch 25 and thereby the interruption of'the running circuits and the establishment of the circuits required for inching movement of the cylinder.

The normal movement of the cylinder is over and toward the operator or in a counter-clock wise direction. as shown in I'igs.,5 and "l, and the description of the following circuit which refers to the movement of a single pocket.

can be amnned as referring to the movement requiredfortheloadingof any orallofthepockets as the same circuit is needed for each pocket moved to the unloading and subsequently to the Cylinder unloading circuit-From source Ll through line "I, pilot fuse,,l*ne I52, safety switch 52,- line I55, transfer switch 25, now in inching position, line "5, door switch 25, now closed, line I'II,line "2, contacts ll of drum 2|, line-I'll, contacts of push button 25, depressed by operato line I'll, line I15, normally closed contact of transferrelay, line 1", line I21, coil Eofcontactonline I85, line I55, line I85, line III, safety switch 52, line 2, overload relay contact, line III, pilot fuse, line lit, to source L5.

The closure of push button 25 by the operatorenergizes the coil of the forward contactor and causes movement of the cylinder drive motor (9) and consequently of the cylinder of the machine in the desired direction, such movement continuing while the operator maintains the push button depressed within the limits fixed by contacts 3I which are normally closed and which open when the cylinder has rotated through the maximum safe movement.

The opening of contacts 3I is caused mechanically by the cylinder reaching a fixed point and the circuit is interrupted at this point irrespective of whether the operator maintains the push 5 button depressed or not. The purposeof this being to prevent excessive movement of the cyl-" inder and consequent possible damage to the machine or the goods being discharged from same.

The foregoing of course presupposes the manual opening of the cylinder door before the movement outlined is effected.

, The cylinder movement outlined is repeated for as many as there are divisions in the cylinder or until such timeas the load is entirely discharged.

The next step is then to recharge .the cylinder with work to be processed and this is accomplished through the circuit:

Cylinder loading circuit.From source LI, line IOI, pilot fuse, line l02, safety switch 52, line 103, transfer switch 25, line I10, door switch 26, line. "I, line I12, contacts 30, line I18, push button 21, closed by operator, line I18, line I80, line I15, normally closed contact of transfer relay, line I11, line I31, coil E of contactor, line I38, line I34, line I35, line III, safety switch 52, line II2, overload relay contacts, line II3, pilot fuse, line I to source L3.

The difference in effect between this circuit and the one immediately preceding is in the fact that a separate set of switches is utilized to prevent cylinder movement beyond a predetermined point, the position in this case differing from the predetermined point established by contacts 3| and fixing the dumping movement limits.

In the case of both the circuits for the obtaining of the dumping and loading-positions the brake must be released coincident with the enersizing of the cylinder drive motor 9 and this is accomplished through the circuit:'

From source LI, line IOI, pilot fuse, line I02, safety switch 52, line I03, transfer switch 25, line I10, door switch 26, line I'II, line I12, contacts 30 or 1, lines I13 or I18, pushbuttons 21 or 28, lines I8I 0r HIS-I81, I82, I83, I84, I85, line I22, brake coil 23, line I28, line I09,'line' IIO,

' line II I, safety switch 52, line I I2, overload relay contacts, line I I3,.pilot fuse, line II to source L3.

This circuit for the release of the brake is duplicated to release the brake under the conditions outlined in the following when it is assumed that for pertinent reasons it is desirable to move the cylinder in a direction opposite to that normally used in the dumping and loading cycle.

The circuit through which this cylinder reversal is accomplishedis as follows:

From source LI, line IOI, pilot fuse, line I02, safety switch 52, line I03, transfer switch 25, line I10, door switch '28, line I1I, line IIII, push but ton 23, depressed by the operator, line I32, normally closed contact of transfer relay, line I93, line I33, coil F of contactor, line I34, line I35, line I I I, safety switch'52, line I I2, overload relay contacta, line II3, pilot fuse, line Ill to source L3.

It will be noted from the connectionfdiagram that this circuit energizes the contactor coil F other than that E usedfor the normal inching of the cylinder and provides for reverse movement reaching a predetermined position, is old in the art and has been disclosedas part of the R. G.
